Still, if the library needs sample rate conversion, the clone plug-in action in Reaper4 using ctrl-drag waits for the sample rate conversion instead of using the already converted one in memory. If the sample rate converted version could be reused, the whole project loading time will be A LOT less.

Wouldn't it be nice if paying customers would also get what is in the free version?

Nebula3 FREE is a DEMO of the present product that is under develop. We will add any new feature in Nebula2/3 and Nebula3 PRO that can both COREs support for free but if you want to have shared memory optimizations you must product upgrade to Nebula3 Server.
